How To Jailbreak The Iphone 3G with Redsn0w

Hey everyone, sorry for not posting in such a long time. I have a good one today for you Iphone users out there.

In today’s article I will explain how I jailbroke my iPhone 3G.

What is jailbreaking you ask?

The jailbreak is a term used to refer to devices that can freely install and run whatever application the user might want or need. Read more on that here

Please understand that JAILBREAKING is not UNLOCKING your device.  Unlocking is when you free the iPhone to run on other cellular carriers other than ATT. Jailbreaking is a risk free process where you will open the OS of the phone to install and run whatever applications you wish. Also, you can ALWAYS restore your device to the factory state using iTunes, which will vanish the jailbreak modifications.
Everything that was working before this process will continue to work, including all the default applications and pre-installed software’s like AppStore and it’s applications. Jailbreaking will simply just open another door for you to choose a path.

Recently I was visited my my brother-in-law and he had just jailbroken his iPhone. I had always thought I might try this one day but I was scared it would mess up a lot of things like my Itunes account, syncing, corrupt the phone OS, slow the phone down, etc. He showed his phone to me and it was totally fine. He was able to carry on just like before but now there were lots of new tweaks on his phone that I always wanted the iPhone to do, like video record, the ability to block calls like many of my older simpler Nokia cell phones uses to do, and also have a simple battery percentage meter(see below), which just came out on the new 3GS by default but not in the new 3.0 OS update from Apple for the current 3G iPhone. Why Apple Why? See the bottom of this post to see how to enable this nice little feature.


NOTE : iPhone 3G users, you can unlock your iPhone 3G 3.0 using ultrasn0w. Ultrasn0w is Dev Team’s new unlock for iPhone 3.0. Remember, don’t update to future iPhone 3.0 updates without checking here first if you want to keep your 3G unlocked, Apple may permanently block this unlock in their next update 3.01.

Before we begin I must say a few words.
Download the files you need at your own risk, I accept no responsibility if your computer explodes or if it becomes part of a NASA attacking botnet or even worse if your hands fall off mid-way during the use of these files. I do not check these links or archives and I accept no responsibility with regard to the validity of the files, or with other content these links provide or with the content that is on the linked site.
Also do not come crying to me if you cant follow simple directions and your phone becomes a paper weight. Use the following information at your own risk like I did twice already.

Ok… so lets get started!
What you will need:
-for MAC
-for PC

Iphone Firmware

Download iPhone 2G firmware 3.0 (filename: iPhone1,1_3.0_7A341_Restore.ipsw)
Download iPhone 3G firmware 3.0 (filename: iPhone1,2_3.0_7A341_Restore.ipsw)

USB CABLE for Iphone

Iphone Browser – useful tool for manipulation files on the iphone easily

Lets Begin:
Download all these files to your computer in a place you can easily find them, like c:downloads (pc)

Next connect your iphone up to the computer with the USB data cable that comes with the iPhone, and launch iTunes. Complete a full sync and backup.
Once this was completed I navigated to where the backup was located on the computer, and copied the folder where the backup resides to a safe place for that “just in case” scenario that we all hope never happens. Its always good to have a backup!

On a Mac: ~/Library/Application Support/MobileSync/Backup/

On Windows XP: Documents and Settings(username)Application DataApple ComputerMobileSyncBackup

On Windows Vista: Users(username)AppDataRoamingApple ComputerMobileSyncBackup

Next, leave the iPhone connected to the computer and close iTunes. Go to your place where you downloaded redsn0w and the 3.0 firmware.

Launch Redsn0w. Once Redsn0w is open click the BROWSE button and locate your firmware. Example- iPhone1,2_3.0_7A341_Restore.ipsw


Once the firmware has been verified click the Next button to continue.


Make sure Cydia is selected and click the Next button.


With your iPhone still connected to your computer,  make sure its OFF then click the Next button. Hold the top right corner for several seconds until you see the scroll bar to turn it off and wait for it to turn COMPLETELY off.


RedSn0w will now guide you through the steps to get into DFU mode.
-hold down the power button for 2 seconds
-without releasing the power button, alsohold the HOME button (bottom center) for 10 seconds
-without releasing the Home button, release the Power Button BUT KEEP holding the home button for 30 more seconds.




Your iPhone will not reboot.


RedSn0w will then begin uploading the new RAM Disk.


Once this is complete you will be notified that RedSn0w is done. Click the Finish button.
When your iPhone finishes reboot (5 minutes or so…please don’t freak out…be patient).
It will be jailbroken with Cydia on the SpringBoard.


About the Applications installed after you have JailBroken your phone.

Cydia is a software application developed by Jay “Saurik” Freeman for the iPhone OS that serves as a graphical user interface for APT, and in turn, the dpkg package management system. Repositories that are included with Cydia allow for installation of software packages in which most are available to download at no cost. The software packages are downloaded directly to an iPhone or iPod Touch device, and are located in the /Applications directory, in the same location where “Apple native” applications are located.

Using Cydia install a new repository to locate apps.
Open Cydia, choose manage, choose sources, tap Edit in the top right and in the top left you will see Add, tap that and enter the url and click accept on the legal warning. Tap done and done and that’s it. Now install the following.

WinterBoard – WinterBoard is a third party application that enables editing of many display items, such as the background, keyboard, application pictures, Safari, and the lock screen.

Installous – Installous is a third party application that is used to get free cracked applications that are supposed to be paid for. This is highly illegal but people still use it.

Cycorder – Cycorder is an app that enables video recording on the iPhone and iPhone 3G. The video quality is average, but since the camera on both of these devices was not made for video recording, the frame rate on the recorded video can be very low in poor light conditions.

Cool things to do now that you have JailBroken your phone

Enable Battery Percentage Indicator in 3G iPhone OS 3.0

Why Apple decided to make this nice little long awaited feature available to the new Iphone 3GS is beyond me. Oh well, here is one of many ways to accomplish this.

1. First you need to Jailbreak your iPhone as mentioned above.

2. Download the M68AP.plist file from the link:

3. Use iPhoneBrowser to look into your iphone and replace files.

4. Go to /System/Library/CoreServices/

5. Replace the M68AP.plist in the directory with the one you downloaded, by right clicking on the file and choosing replace. Browse to the file you downloaded.

6. Restart you iphone.

7. Now go to the application Settings -> General -> Usage and there will be a Battery Percentage toggle and you can use it to enable battery percentage next to battery icon in top-right corner.

Now is all this legal?

The legality of jailbreaking an iPod or iPhone remains unclear, particularly in the context of the Digital Millennium Copyright Act. As part of the 2009 DMCA rule making, the Electronic Frontier Foundation asked the US Copyright Office to recognize an exemption to the DMCA to permit jailbreaking in order to allow iPhone owners to use their phones with applications that are not available from Apple’s store. In response to this, Apple has filed comments opposing this exemption, and indicating that they do consider jailbreaking to be a violation of copyright (and by implication prosecutable under the DMCA). A ruling on this proposed exemption has not yet been made, but a decision is expected sometime later this year.

I must say that if I were you and paid ridiculous money, which I did,  for a cell phone I would not want to be limited to what all I could do with it!

Happy Hacking!
